Snailshell + Minerva: 1980 Porsche 924 Turbo

Jeff LaveryBy Jeff Lavery

While the early 924s aren’t exactly loved by enthusiasts, the 924 Turbo responded to the naysayers by adding a KKK turbocharger and a number of other engine enhancements to close the gap between it and the naturally-aspirated 911. Visual cues were also part of the package, including a NACA hood duct and air vents in the nose. This example is a 1980 model, a one-year only example with the “snailshell” dogleg transmission. Find it here on eBay with a $1,500 Buy-It-Now.

This seems like a very fair price for a genuine 924 Turbo that remains mostly stock and with the desirable one year-only transmission. The turbocharged model is based on an Audi-sourced VW inline-four with a KKK turbocharger, lower compression and a unique cylinder head. Power was rated at 170 b.h.p., significantly enhancing the 924’s performance over the base model. This car is certainly rough around the edges, and the seller notes the seats are from a 911.

The Minerva Blue paint code is one of my favorites and not often seen. It’s certainly rough on this example, but I’d try to return it to its original colors if possible. Though it’s been parked since the 1980s, the seller notes the turbocharged-mill does still turn over but doesn’t run at the moment. While he’s correct in stating that the dogleg transmission is worth a pretty penny, many of them are also trashed by now due to the unconventional shift pattern – and spares are non-existent.

Though the body will need complete restoration, the seller says there’s very little rust. Overall, these turbocharged 931s are getting rarer by the day, especially the one-year only model like this one with the unique transaxle. Performance is respectable by today’s standards, and while restored examples aren’t worth so much that you couldn’t justify buying a finished one, the low price here makes a project more appealing.

    LS swap. Sell the original powertrain. I think that’s a car that has been flooded with the corrosion present and lack of carpets.

    There was actually a company that called themselves KKK? That’s even worse than DUI ignition parts…..

      KK&K stands for Kühnle, Kopp & Kausch, a German engineering company started in 1899. I don’t think they knew the significance back then.

  3. Beatnik Bedouin

    There’s rot in the monocoque, making this an expensive rebuild for a car that doesn’t have much value.

    It’s a shame, as the 924 Turbo was a much better car than the N/A original….

    As write up mentions an unusual colour thats for sure. Most seem to be red.

  5. Canadian Mark S. Eh!

    So if willing to settle for the ugly duckling version than a Porsche rust bucket is where it should be price wise. First of all I wouldn’t want it but if I did I’d resto mod it with common garden variety gm parts. This is conformation to me on how inflated the prices on Porsches are.

    that gear box is standard Porsche ’79 – ’80, the G31. It’s stronger/lghter/sm than the Audi boxes but with weak and expensive synchromesh in the lower gears.
